Subassembly composer superelevation

[lamichhaneR4TBD]

I created a sub assembly for the Curb and Gutter that has few adjustments than the regular one in C3D. It works fine if I hard code in the superelevation but doesn't work if I leave it blank and chose from the C3D. Just want to be able to use it on both sides using "Left Outside Lane Slope" and "Right Outside Lane Slope".

Attached are the Subassembly and few pictures.

Hi @lamichhaneR4TBD, I hope you are doing well. You can solve that with a variable to store the superelevation value. Check the attached PKT file. I changed the Slope field of your AP1&AL3 point and eliminated the Superelevation you had.

I tested its behavior in the preview window, and it seems to work. See images

However, I invite you to check it in C3D to be completely sure.

I hope this helps. Best regards!

I am unable to load the pkt file in both SAC and C3D. Could you resend it?

Hi @lamichhaneR4TBD, I forgot to mention I used subassembly composer 2025. I’ll post screenshots of the variable so you can recreate what I did. I’m not on my laptop right now but I'll come back to this post as soon as I can. Regards

Hi @lamichhaneR4TBD, I won't attach the PKT file again since, as I mentioned, I used a different version of the software, and it won't work on your PC unless you install Civil 3D 2025. However, I will provide all the details of what I did to your PKT so you can reproduce them.

This is what I did to your subassembly:

1. I created a new variable for DefaultSlope. I placed it at the beginning of the flowchart since I consider it the best place. However, you can place it anywhere else as long as it is before the point/link you will use it in.

2. Then I inserted a new variable, Superelevation

This is the code for the variable (copy and paste to your subassembly):

IF(SA.IsLayout=True, ctype(DefaultSlope,double),
IF((UseSuperelevation=LeftInsideLane) AND (SE.HasLeftLI) , SE.LeftLI ,
IF((UseSuperelevation=LeftOutsideLane) AND (SE.HasLeftLO) , SE.LeftLO,
IF((UseSuperelevation=RightInsideLane) AND (SE.HasRightLI) ,SE.RightLI,
IF((UseSuperelevation=RightOutsideLane) AND (SE.HasRightLO) , SE.RightLO,
IF((UseSuperelevation=LeftInsideShoulder) AND (SE.HasLeftSI) , SE.LeftSI,
IF((UseSuperelevation=LeftOutsideShoulder) AND (SE.HasLeftSO) , SE.LeftSO,
IF((UseSuperelevation=RightInsideShoulder) AND (SE.HasRightSI) , SE.RightSI,
IF((UseSuperelevation=RightOutsideShoulder) AND (SE.HasRightSO), SE.RightSO,ctype(SubbaseSlope,double))))))))))

3. Assign the "Superelevation" to the Slope field, and remove the superelevation you had assigned before

4. Test the geometry in the preview window and in Civil 3D

I hope this helps.

Best regards!
